获取单元格 apache poi 的名称 [英] Get name of cell apache poi

问题描述

我有一个 Cell 对象，我怎样才能得到那个 Cell 的名字?

I have a Cell object, how can I get the name of that cell?

想要一个函数，例如:

String name = myCell.getName();

在Excel中我已经在名称框中命名了，所以我不想得到'B4'，我想得到诸如InterestRate"之类的名称.

In Excel I have named it in the name box, so I don't want to get 'B4', I would like to get the name such as "InterestRate".

找不到这样的方法，能不能用别的方法实现?

Can't find such a method, can I achieve it in some other way?

推荐答案

要查找定义为与一个单元格完全匹配的命名范围，您需要如下内容:

To find the named range which is defined to exactly match one cell, you'd want something like:

// Get the cell we want to find - A1 for this case
Workbook wb = WorkbookFactory.create("input.xlsx");
int sheetIndex = 0;
Sheet s = wb.getSheetAt(sheetIndex);
Cell wanted = s.getRow(0).getCell(0);
String wantedRef = (new CellReference(wanted)).formatAsString();

// Check all the named range
for (int nn=0; nn<wb.getNumberOfNames(); nn++) {
   Name n = wb.getNameAt(nn);
   if (n.getSheetIndex() == -1 || n.getSheetIndex() == sheetIndex) {
      if (n.getRefersToFormula().equals(wantedRef)) {
         // Found it!
         return name.getNameName();
      }
   }
}

请注意，这将返回适用于单元格的第一个命名范围，如果有多个并且您想要全部，则需要调整该代码以继续并返回列表

Note that this will return the first named range that applies to a cell, if there's more than one and you wanted them all, you'd need to tweak that code to keep going and return a list
